It is very “refreshing” drink with a big, nuclear kick. LIIT has some variations, which I try too.

Variations:

Long Beach Iced Tea: Simply a Long Island with cranberry juice instead of Coca-Cola. Named after the city of Long Beach, NY, (not Long Beach, CA, as many believe) which is on Long Island, and is where the drink was invented.

Adios Motherfucker: Also known as a “Code Blue” or “Blue Fucker” due to its azure hue, this concoction is topped with Sprite (or another lemon-lime soda) instead of Coca-Cola and use blue curacao liqueur instead of triple sec (Cointreau).

Actually I am not of the LIIT lovers too. But it is one of classic (“modern classic” of course) cocktails and I try it. I think it is very commercial drink and it has success in many bar.
The variations of LIIT are totaly awful drinks and must serve only 18 y.o. man :) (21 y.o. in USA).
And Bullfrog sounds like totaly shit :)

I think all LIIT’s supposed to be served to adults (may be it could be better to wait for a 30 to drink this drinks – on the other hand, those supposed to be already old enough to refuse recipes like that – uh no… some are never old enough!).

Fill a sling glass to the rim with ice cubes. Pour absolut vodka, lime juice, plymouth gin, simple syrup and triple sec into a shaker. Fill the shaker with ice cubes and shake it until the shaker is very cold. Strain the drink into the sling glass. Top up with champagne. Garnish with a lime (wedge).

I agree LIIT and its variations are by no means good/classy/tasty, but it is VERY popular. Along with its variations ofc., so it really pays to have a “heavy” section on your cocktail menu if you run a bar. And don’t judge 18yr-olds too fast :) I’m 18 and im more of a MaiTai/Mojito fan
